  9. Procédé selon la revendication 8,
    la tension de sortie (Vout) étant mesurée directement ou indirectement et converti en valeurs numériques et
    pour la régulation du courant secondaire (I2), la durée de décharge (Tdischarge) entre une désactivation du commutateur (M1) et une chute suivante du courant secondaire (12) à zéro est mesurée en fonction des valeurs numériques.
